Abstract

The invention discloses a data center, comprising a cabinet and at least one server system, wherein the cabinet is provided with an elevated floor, and the at least one server system is arranged in the cabinet; the server system comprises multiple severs at different heights; and the elevated floor has a ventilating grate hole. The cooling system used for the data center comprises an air conditioner, multiple temperature sensors respectively arranged nearby the exhaust ends of the servers, a group of guide fans arranged nearby the ventilating grate hole of the elevated floor, and a control module electrically connected with the air conditioner, the temperature sensor and the guide fans, wherein the cool air from the air conditioner is injected below the elevated floor; the guide fans can drive the cool air to pass through the ventilating grate hole to flow upwards at an acceleration mode; and the control module adjusts the rotation speed of the guide fan based on the temperature value acquired by the temperature sensor, so as to enable the cool air to be uniformly distributed, and servers at different heights to uniformly cool. Compared with the prior art, the data center provided by the invention can improve the cooling efficiency, so as to save energy.

Example Embodiment

[0029] Please refer to figure 1 The preferred embodiment of the data center of the present invention includes a cabinet 10 and a server system 20 arranged in the cabinet 10. The number of server systems 20 can be one or more, figure 1 Only one server system 20 is shown in, and only one server system 20 is used as an example for description. In this embodiment, the cabinet 10 is a container that can be transported by a vehicle. A raised floor 11 is provided in the cabinet 10. The raised floor 11 is provided with a ventilation grill hole 112 adjacent to the intake end of the server system 20. A set of diversion fans 114 is provided between the raised floor 11 and the bottom plate of the cabinet 10 aligning with the ventilation grill holes 112 of the raised floor 11. In this embodiment, the number of guide fans 114 is three, and each The distance between the guide fan 114 and the server system 20 is different.
[0030] Each server system 20 includes a rack 21 and a plurality of servers 23 installed in the rack 21. The frame 21 is provided with a plurality of receiving cavities 211 along its height direction. The servers 23 are respectively placed in the receiving cavities 211. The rack 21 is also provided with partitions 213 and anti-backflow gates 215 at the inlet and outlet ends of each accommodating cavity 211, which are used to prevent the hot air discharged from the server 23 from flowing back to the inlet end of the server 23. 23 Inhalation. Each server 23 is provided with a fan and a temperature sensor 233 arranged near the exhaust end of the server 23 for sensing the temperature of the hot air discharged from the server 23.
[0031] See also figure 1 and 2 The first preferred embodiment of the heat dissipation system of the data center of the present invention includes the guide fans 114, the temperature sensors 233, an air conditioner 40, and a control module 50. The cold air generated by the air conditioner 40 is injected between the raised floor 11 and the bottom plate of the cabinet 10 and can flow upwardly from the ventilation grill holes 112. The guide fans 114 drive the cold air to flow upward. When the speed of the guide fan 114 is increased and the speed of the guide fan 114 farther from the server system 20 is greater than the speed of the guide fan 114 closer to the server system 20, more cold air is sent to the upper layer of the cabinet 10 The space is advantageous for the server 23 on the upper floor to take in cold air. The control module 50 includes an arithmetic unit 51 and a driving unit 53 electrically connected to the arithmetic unit 51. The control module 50 is electrically connected to the guide fans 114, the temperature sensors 233 and the air conditioner 40. In this embodiment, the arithmetic unit 51 is electrically connected to the temperature sensors 233 to read the temperature values ​​sensed by the temperature sensors 233 and compare the temperature values. When the temperature of the hot air discharged by the upper server 23 is greater than the temperature of the hot air discharged by the lower server 23, the arithmetic unit 51 sends a control signal to the driving unit 53, and the driving unit 53 accelerates the farthest distance 20 according to the control signal. The rotation speed of the guide fan 114 sends cold air into a higher space, so that more cold air flows into the upper server 23 to achieve uniform heat dissipation of the upper and lower servers 23.
[0032] See image 3 The second preferred embodiment of the heat dissipation system of the data center of the present invention includes the guide fans 114, the temperature sensors 233, the air conditioner 40, and a control module 60. The control module 60 includes a computing unit 61, a driving unit 63 electrically connected to the computing unit 61, and an input unit 65 electrically connected to the computing unit 61. The control module 60 is electrically connected to the guide fans 114, the temperature sensors 233 and the air conditioner 40. In this embodiment, the input unit 65 can be used to input a temperature range, the upper limit of the temperature range represents the maximum allowable value of the exhausted hot air temperature of the server 23 during normal operation, and the minimum value of the temperature range represents reasonable performance. The minimum value of the temperature of the hot air discharged by the server 23 under the consumption requirement, that is, when the temperature of the hot air discharged by the server 23 is lower than the minimum value, it is considered that the amount of cold air passing into the server 23 is excessive. The computing unit 61 is electrically connected to the temperature sensors 233 to receive the temperature values ​​of the corresponding server 23 sensed by the temperature sensors 233, and compare each temperature value read with the temperature range input in the input unit 65. When the temperature of the hot air discharged from the upper server 23 is higher than the upper limit of the temperature range and the temperature of the hot air discharged from the lower server 23 is lower than the lower limit of the temperature range, the driving unit 63 drives the farthest distance from the server system 20 The guide fan 114 speeds up to send more cold air into the upper space of the server system 20, and the drive unit 63 drives the guide fan 114 closest to the server system 20 to slow down the speed to reduce the space sent to the lower layer of the server system 20 Air-conditioning. When the temperature of the hot air discharged from all servers 23 is higher than the upper limit of the temperature range or lower than the lower limit of the temperature range, the driving unit 63 adjusts the air conditioner 40 to increase or decrease the total cooling capacity.
